Technical Features
Valve Regulated Design
The batteries are equipped with a simple, safe low pressure
venting system which releases excess gas and automatically
reseals should there be a build up of gas within the battery due
to severe overcharge. Note. On no account should the battery
be charged in a sealed container.
Lead Calcium Grids
The heavy duty lead calcium alloy grids provide an extra margin of
performance and life in both cyclic and float applications and give
unparalleled recovery from deep discharge.
Sealed Construction
Yuasa’s unique construction and sealing technique ensures
no electrolyte leakage from case or terminals
Long Cycle Service Life
Depending upon the average depth of discharge, over a
thousand discharge/charge cycles can be expected.
Electrolyte Suspension System
REC batteries utilize Yuasa’s unique electrolyte suspension
system incorporating a microfine glass mat to retain the
maximum amount of electrolyte in the cells. The electrolyte
is retained in the separator material and there is no free
electrolyte to escape from the cells. No gels or other
contaminants are added.
Float Service Life
The expected service life is seven years in float standby
applications at 20°C.
Control of Gas Generation
The design of Yuasa’s REC batteries incorporates the very
latest oxygen recombination technology to effectively
control the generation of gas during normal use.
Long Shelf Life
The extremely low self discharge rate allows the battery to
be stored for extended periods up to one year at normal
ambient temperatures with no permanent loss of capacity.
Low Maintenance Operation
Due to the perfectly sealed construction and the
recombination of gasses within the cell, the battery is almost
maintenance free.
Operation in any Orientation
The combination of sealed construction and Yuasa’s unique
electrolyte suspension system allows operation in any
orientation, with no loss of performance or fear of electrolyte
leakage. (Excluding continuous use inverted)

Separators
The use of the special separator material provides a very
efficient insulation between plates preventing inter-plate short
circuits and prohibiting the shedding of active materials.

TYPICAL DISCHARGE CHARACTERISTICS NP RANGE
SELF DISCHARGE CHARACTERISTICS
Charging For Float Standby Applications
Charged at 2.275 volts per cell continuous. The battery will
seek its own current level and float fully charged. However,
users should be aware that when charging from fully
discharged, the battery can draw an initial charge current of
approximately 2cA. Care should therefore be taken to
ensure that this initial charge current (if ungoverned) is
within the output capability of the equipment. Final charge
current at 2.275 volts per cell is typically between 0.0005cA
to 0.004cA.
Charging For Cyclic Applications
See cyclic recharge regime graph.
Operating Temperature Range
The batteries can be used over a broad temperature range
permitting considerable flexibility in system design and
location.
Charge
– 15°C to 50°C
Discharge – 20°C to 60°C
Storage
– 20°C to 50°C (fully charged battery)
CAUTION
- Do not Short Circuit
- Do not charge in a sealed container
- Service life and operational characteristics will
be affected by temperature
- AC Ripple reduces service life.
